Shops have value on many different levels. There is the satisfaction of having a place to create and work on projects that is hard to quantify, but definitely improves your quality of life. There is the value to your small business of having space in which to work wood and thereby generate income. There is the dollar value of the build itself, which will be a considerable investment and, finally, there is the resale value of your property after you’ve added your shop. Before you go too far, though, it’s worth asking a local real-estate agent about the potential return on your investment in your area; generally shops won’t add significantly to the value of your property, so it’s worth thinking carefully about what else the space could be used for if you were to sell. The decision about whether it is worth it to build is a matter of balancing all these factors: projected sales balanced against the cost; the cost of building is balanced against what it will be worth when you sell. Woodworking can be a creative outlet, can give you a sense of mastery, and even be a way to give back to your community by donating beautiful pieces to local charities for fundraising auctions, or creating pieces that future generations will inherit. Ultimately, the value of a shop might come down to the emotional and social returns that it will pay you and the people around you for years to come.
Shop layout is all about making the best use of space. Place your machines so that you have adequate “safe space” that you need to work around them. The “buffer area” beyond that is the amount of room you need to run large stock though a given machine, keeping in mind that buffer areas can overlap between machines. If you want to get more organized, buy some 1/4-inch squared paper, make scale models of each machine including the safe space around each, and place them on your model shop layout. Remember that buffer areas need to be long enough to put an 8' sheet through a table saw, or a 6' plank through your planer, for instance. I raised my planer, so that I can use the area above my router table to pass long planks through the planer – all it takes is some modelling, and a little shuffling, and you will find the layout that works for you. Each space will have challenges; I had the area under the stairs that was wasted space, so I installed the dust collector there.
Old doors laid across sawhorses make great temporary workbenches, but they take up a lot of space when you’re not using them. Instead of full-size doors, I use bifold doors with hinges so I can fold them up when I’m done working. They’re also easier to haul around in the pickup for on-the-road jobs. — Harry Steele. Here are 12 more simple workbenches you can build.
Alternately, a detached shop can often be located closer to your property line and offers you a bit more freedom in terms of the type of foundation you can use. It may give you a sense of welcome separation from your home and open up yard space or allow a deck on the back of your house that would otherwise be lost behind your shop. In an urban setting, if you would like to have a wood stove in your shop you may find it more challenging to find an insurance carrier that allows one in an outbuilding. Also, outbuildings can be subject to more stringent height regulations than additions.
As the comic George Carlin might say, a shop is mostly just “a place to put your stuff.” The physical aspect of a shop is indeed simply a space of some kind — a garage, a barn, a teepee — that keeps the rain, rust, and robbers away and houses a collection of implements needed to saw, plane, slice, sand, and pound raw wood into useful objects. But just like the difference between a house and a home, what transforms a building full of tools into a comfortable workshop goes beyond the mere physical aspect.
